The INFINIUM 3G-SDI HEVC Encoder Card connects the professional broadcast world to the INFINIUM chassis. With a locking 3G-SDI BNC input and embedded audio, it is built for live production, sports venues, houses of worship, and broadcast headends where SDI is the standard. HEVC encoding keeps bitrate low so your SDI sources reach a far larger audience over IP.
3G-SDI HEVC Encoder Card
Bring Broadcast SDI Into Your Headend
The professional choice for SDI workflows. Accept any 3G-SDI HD feed from cameras, switchers, and routers, and encode it efficiently with HEVC for streaming and distribution.
Capabilities
SDI In, Everywhere Out
Take a professional SDI feed and deliver it to players, set-top boxes, smart TVs, browsers, and global platforms — all at the same time, each in the right format.
- Four simultaneous streams — different compression & resolution each, with logos & watermarks
- SRT ultra-low latency down to 50 ms · RTMP, M3U8, HLS, HTTP, UDP, RTP, RTSP, ONVIF
- Built-in unicast server · multicast (IGMP v1/v2/v3) to unlimited devices
- Stream direct to YouTube, AWS, or Facebook — and to several platforms at once
- Auto-reconnect and SRT decoder compatibility (VLC and our VePlayer)
IP + Coax
From the Truck to Every Screen
Stream SDI sources over IP for live production and contribution, and pair with the 4K-over-coax module to deliver the same channel over existing coax to any television in the venue.
Ideal for live events, the 3G-SDI card ingests camera and switcher feeds and streams them anywhere over IP, while the chassis 4K-over-coax module can simultaneously deliver the same channel over existing coaxial cabling to every TV in the building. One SDI source, infinite reach.

FAQ
INFINIUM 3G-SDI Card — FAQ
What sources work with the 3G-SDI card?
Any 3G-SDI HD source — broadcast cameras, production switchers, routers, and converters — with embedded audio over a single locking BNC cable. It is the professional alternative to the HDMI cards for live production.
Why is SDI preferred for live production?
SDI uses locking BNC connectors and supports long, reliable cable runs, making it the standard in broadcast trucks, stadiums, and studios. This card brings those professional feeds straight into the INFINIUM headend.
Does it support HEVC?
Yes. It encodes in HEVC, H.264, or MJPEG. HEVC delivers the same quality at roughly a quarter of the bitrate, ideal for streaming SDI sources to large audiences.
Can it stream with low latency?
Yes — SRT ultra-low latency down to 50 ms plus network travel time, alongside RTMP(S), HLS, HTTP, RTSP, RTP, FLV, ONVIF, and UDP/RTP unicast and multicast.
Can I mix SDI and HDMI cards in one chassis?
Absolutely. Populate a single INFINIUM chassis with any mix of 3G-SDI, HDMI HD, 4K30, and 4K60 cards to match every source in your facility.
Can I distribute SDI channels over coax?
Yes — add the INFINIUM 4K-over-coax module to the chassis and the SDI-sourced channel is delivered over existing coax as a digital TV channel to any television.
Does it require the INFINIUM chassis?
Yes. It installs in the INFINIUM 4K Video Distribution Chassis, which provides power, cooling, redundancy, and the network/RF backplane.
